Application filed March 20, 1916. Serial No. 85,295.

To all whom it may concern Be it known that I,

at Hartford, co lnty of Hartford, and State of Connecticut have invented certain new and useful Improvements in Wrapping-Machines, of which the following is a full,

clear, and exact description.

This invention relates to machines for wrapping tire casings and similar articles, the wrapping of whichis usually applied in spiral form. v

,One of the objects of my invention 1 s to provide a machine of the type described combining a simple and inexpensive mcchanism for applying to the surface of the therein partlybroken away and in the act v of receiving a wrapper and a tearing-strip; and

Fig. 2 is a partial sectional elevation. taken on line 2 2, of Fig. 1.

Referring now to the drawing the numeral 1 designates the frame of the machine,

the upper portion of which is formed into two ,qrooved jaws 2 and 3 providing a substantially circular guide way for an annular shuttle 4. mounted therein. Mounted on the inner face of the shuttle 1 is a roll of paper 5 from which the wrapper is pulled and wound about the tire upon rotation or the shuttle.

The shuttle is adapted to be driven by means of a friction wheel 6, mounted to rotate on the shaft X, which receives power from a drive pulley acting through a friction clutch 8 and foot treadle 9. Spaced about guide way formed by the jaws 2 l 1 d 11 and 3 are idier guide wheels 9, an

fiisposed in parallel horizontal sleeves or bearings iixed to the frame 1 are shafts 12 and 13 upon each or which is mounted :1

CHARLES B. WHrrrrJL- car, a citizen of the United States,'res1d1ngsleeve 14 having formed integral therewith a flange 15. Beyond each flange 15 the sleeve 14 is enlarged and upon it is mounted a ring 16 adapted to slide back and forth through a plunger and an adjustable lever attachment, as shown, each ring 16 being provided with a flange 17 adapted to coact with flange 15 to hold a tire therebetween.

The tire may be inserted in place by re moval of the segment 18 of the shuttle andwhen introduced through the opening thus mademay be positioned between the flanges 15and 17 as indicated. In this position it is adapted to receive paper from the roll 5, the paper passing over a device for turning the edge thereofand a series of guide rollers 19, 20 and 21, disposed upon a bracket and arm support 22 attached to the inner face of the shuttle 4. Upon rotation of the shuttle,

paper will be fed to the tire, which will be gripped between the flanges 15 and 17 and rotated upon rotation of the shafts 12 and 13. The latter are provided with worm wheels 23 and 24 adapted to be driven by worm gears mounted on the shaft 7.

A roll of gummed paper 25 is mounted on a removable shaft carried in the slots of a bracket 26 positioned adjacent the extremity of theupper jaw 2. T Tension is applied to the out r surface of the roll by means of a lever 27 held n place against the paper by a spring 28. The gummed paper wound-on the roll 25 is of a material having greater tensile or tearing strength than the strip of wrappin material wound spirally about the tire. This tearing strip has an adhesive substance such as glue or paste applied to its surface, and the spiral wrappings are placed over the same when the paste or adhesive is in a moist condition. In this manner all of the convolutions or turns of the wrapper are securely fastened together to prevent slipping thereof with respect to one another. One end' of the longitudinal strip is allowed to project from beneath two of the convolu- 1 tions to provide an end by which the strip may be grasped when the covering is to removed from the tire. Upon pulling this strip the convolutions of the wrapper will be torn but will adhere to the tearing; strip so as to prevent the pieces of the wrapper from being scattered about. 7

Mounted below the roll 25 and on the side of the jaw 2 is a bracket 29 provided in the: lower portion thereof with a water recep- .plied by means of the foot treadlc 9.

tacle 30 removably mounted in which is a. metal roll 3lsupp0rted in grooved slots. Held in the outer extremity of the bracket 29 is a moistening roll 32, over which the paper strip passes on its way to the tire. The flanged roll 3:! is provided with an absorbent material as felt for retaining the moisture supplied thereto from the trough 30. The roll is loosely mounted on the shaft 33 and is free to adjust itself laterally with respect to the supporting arms of the bracket.

Supported intermediate rolls 31 and 32 by links 34: each having one extremity loosely fitting about the shaft 33 is a felt covered roll 35 supported by an axle 36 held by the ends of the links 34 opposite their engagement with the shaft The breadth of the roll 35 is such that it may rest between and be guided by the flanges 0.1 the roll The space between these flanges is approximately the same as the width of the adhesive paper, and it will readily be seen that any lateral adjustment of position of the roll 32 wiii auton'iatically carry the roll 35 therewith.

A pet cock 37 is provided to permit the withdrawal of water from the trough 30. A removable drip-pan 38 is also attached to bracket 29, serving to prevent any dripping on the tire being wrapped.

Viater being supplied to the roll 35 by the roll 30 and thence to the absorbent sur face of the roll will serve to moisten the adhesive surface. of the paper strip passing about the roll 3:2. The strip thus moistened will pass over a guide roller 39 supported thence will pass to a position to be attached to the paper which is being wrapped about the tire. The roll 39 is so positioned that the tearing strip is applied to the wrapper from a point to the rear (with respect to the. direction of the rotation of the tire) of the point of application of the wrapper".

The devices referred to for applying the wrapper and the tearing strip are so arrangcd therefore that the coil of paper be.- ing wound about the tire is brought into surface contact with the adhesive strip at the instant this portion of the coil of paper is laid upon the tire.

In operating the device the tire is positioned between the flanges 15 and 17 as hereloforc. indicated. Paper from roll 5 is led to a position to he applied to the tire and the adhesive strip. having been moistt cd by turning the roll 32 for a few revolutions by hand. is brought to a position for attachment. to the wrapping strip. Power is ap- The wrapping of the tire by paper from the roll .5 will proceed. with the rotation of the shuttle and the simultaneous rotation of the tire, in a spiral course. from the roll 25 will be attached as the The adhesive strip wrapping progresses to the inner face of the wrapping paper. being drawn from the roll 25 as required by the rotation of the tire.

While I have described the tearing strip coming from roll 25 as an adhesive strip and the receptacle 30 as containing water]: do not wish .to be limited to this adaptation-of the. apparatu. as it will be obvious that I may use a plain non-adhesive strip and that in such case the tank 30 may contain an adhesive liquid to be applied to the strip as it passes over the roll Having thus described my invention what I claim as new and desire to protect by Letters Patent is:
